Biography
Gradin was appointed as the commander of Navassa, a fortress island of Great Britain that controlled the waters around Jamaica. Navassa was heavily-defended, but in January 1717 pirate Edward Kenway and the ship "Jackdaw" destroyed the defenses, before storming the fort. Kenway alone entered the war room and used his hidden blades to assassinate Gradin, who was begging for mercy.
